To all lwhom t may concern.'

Be it known that I, JOHN'H. ETTER, a citizen of the United States, residingl yat Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Manifold-Heating Devices, of which the following is a specification.

The present invention relates to heaters primarily adapted -for heating the intake pipe or manifold of an engine to retain the charge vaporized until the same enters the cylinders, thus preventing any difficulty being experienced in the starting operation of explosive engines for motor vehicles.

An object of the invention resides in the production of a heater of the above stated character, which is simple in construction, durable in use, and so constructed to effectively and expeditiously heat the manifold of an explosive engine, by the admission of cold air within the heater and discharged against the manifold of the engine in a heated condition.

To this end, use is made of a heater of hollow formation provided at one end with a closure so constructed to permit of the air entering the hollow body portion of the heater through said closure and the currents of air discharged from the opposite end of the body portion and against the manifold of the engine in a heated state in order that the charge will be vaporized until it enters the cylinder.

With the above and other objects in view,

the invention consists in the novel features,

details of construction and combination of parts which will hereinafter be more fully set forth, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings:

Figure 1 is a side elevation of a portion of an explosive engine, illustrating the heater engaged against the manifold of such engine;

Fig. 2 is a perspective view of the heater;

Fig. 3 is a longitudinal sectional view; and

Fig. 4 is a view similar to Fig. 2 illustrating the closure in open position.

Referring more particularly to the acco1npanying drawings, in which like characters of reference refer to corresponding parts in the several views, my improved heater is denoted generally by thecharacter 5 and is preferably constructed from a single blank' of sheet metal bent to provide the heater fwith a hollow cylindrical body portion 6. The end of the body portion 6 is downwardly and outwardly inclined to provide the heater with a conical discharge spout 7 formed with a contracted discharge opening 8, while the open end 9 of the body portion 6 serves as an inlet for the heater. The character 10 indicates a handle secured exteriorly of and to the side of the body portion 6 to serve as convenient means for conveying or holding the heater against the manifold A of the explosive engine B when it is desired to heat the intake pipe of the engine to facilitate the rapid starting of such engine. The body portion 6 and the spout 7 are covered with a suitable piece of asbestos 11 in order that the heater will not be exposed to the atmosphere and thus retain the heat within said heater.

A closure 12 is connected to the inlet end 9 of the body through the medium of a suitable hinge 13 mounting the closure on said body for vertical swinging movement. A suitable keeper 14: is secured to the closure and adapted to coperate with a lug 15 provided on the exterior portion ofthe body to hold the closure in'closed position. The chief characteristic of my invention resides in the provision of an improved heater wherein its closure 12 has connected to the inner face thereof, a torch 16, through the medium of a suitable wire mesh 17. The torch is formed of any suitable material and adapted to be saturated with gasolene, wood alcohol or the like, thus upon the lighting of the torch and closing the closure 12, the heater will be readily heated in order that the currents of air passing within the heater through the openings 18 of the closure may be discharged through the outlet end of the spout and directly against the manifold of the engine in a heated state. These openings 18 are disposed in a concentric series y and encircling the torch, as clearly shown.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of construction and the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principles of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it known that the device shown is merely illustrative, and that such changes may be inade When desired as are Within the scope of the appended claim.

Having thus described the invention, I claim:

AA portable heater comprising a hollow cylindrical body portion, an inclined cone-V shaped spout formed contiguous With the upper end ofrsaid body portion and the contracted end of said spout providing an 10 outlet, a covering for said body and spout,

-an apertured' closure hinged to the lower JOHN H. ETTER.
